Product Description

Classic Wimshurst Machine:

This Wimshurst Machine by Active Statics Classic™ impresively demonstrates the principles of electrostatic induction. As the two discs start to rotate in opposite directions, a small but opposite charge is induced from one metal sector facing it's counterpart. As this process is repeated, negative charges build up on one side and positive on the other. These charge are collected and distributed to two capacitors (Leyden jars) at the front of the machine. Once the capacitors reach their storage limit, all of the collected electricity is discharged at once resulting in sparks up to 5 inches in length at a voltage of 250kV.

Our Classic Wimshurst Machine is modeled after electrostatic machines of the 1800's, which were vital to the dscovery of much of what we know about electricity today. Although our Classic Wimshurst Machine appears to Victorian in design, we use PMMA clear plastic to construct out discs and conductive plastic for the charge collection brushes. Modern materials result in a much higher yielding and efficent machine than what was available in years past. 

Top educational and research instututions use Wimshurst  machines to this day as teaching aids and demonstrations in the felds of electrostatics and physics.


  • 250,000+ Volts
  • 5+ inch Sparks.
  • 2 12 inch contra-rotating disks with metal sectors ensure electrostatic induction on demand.
  • Antique, 1800's appearance.
  • Features conductive plastic charge collecting brushes which will not scratch disks.
  • Rigid Victorian styled  disk supports and beautifully vaneered wood base make for authentic styling. 
  • Adjustable spark gap. Smaller gaps allow for more feequent sparks, while wider settings allow for long but slightly less frequent discharges. 
  • 2 Banana jacks allow you to connect test leads - light up xexon flash bulbs, neon lamps, see electrostatic coronas in a dark room!
  • The perfect gift for Star Trek fans of all ages or sparking a child's interest in science!

Although the Wimshurst machine was not the first electrostatic machine to produce high voltages, it gained such widespread use in labs due to the fact that it self-startes, thanks to the metal disk sectors which induce currents quickly. 

The Classic Wimshurst Machine is our first model in this category. We confidantly believe James Wimshurst would find this machine impressive.
